Pick a mode. Room modes: source through the mains (mics muted), phone at ear height in the audience area. Cyan ticks on the graph = last measurement at this venue.
Room advice covers 100 Hz–12.5 kHz only (phone mics are unreliable outside that). Measure 3–4 spots; only problems seen at half or more of them are reported. Cut, don't boost; 3–6 dB max. Trust your ears last. Insert a GEQ on Main LR via the X32 FX rack, or use the main PEQ.
